Replace @{name} with ${name} to be consistent with the rest

[keyboardq] Move to using a Drawer

Note that in 3.2 branch, the version in CMakeLists now changes just before
the next release, not in post-release housekeeping. That is because
the CALAMARES_VERSION_RC remains 0 (release mode), by convention.

(cherry picked from commit c8eec51c)

(cherry picked from commit f2121197)

no longer use a ComboBox or stack view
if accepted, other QML models using a ComboBox will move to Drawer too

toml is needed for greetd, but that shouldn't stop the tests
from running.

This is basically PR #2002, from Undef-a.

Since this CMakeLists.txt writes out a C program, the formatting
is a bit weird; just start the written TU with a blank line to
make gersemi happy and keep the C-code aligned.

To avoid git complaining about duplicate worktrees, detach
the temporary trees. To avoid python modules translations
changing order (depending on how find traverses the tree),
sort the filenames before extraction.

This fixes all the **tests** of locale-detection. Now we can
test for user interaction.

- Esperanto now doesn't quite self-match because it has no country
- sr prefers RS as country over ME

- prefers language default country (ca_ES over ca_AD)
- prefers non-empty country match

Prefer "en_US" over "en" even when asking for "en".

- find the best score and match relative to a specific
  set of parts; make it easy to update the country-setting
- look for a complete match, or best match, with three
  country settings
